Problem description

A vulnerability was discovered and corrected in newt:

A heap-based buffer overflow flaw was found in the way newt processes
content that is to be displayed in a text dialog box. A local attacker
could issue a specially-crafted text dialog box display request
(direct or via a custom application), leading to a denial of service
(application crash) or, potentially, arbitrary code execution with the
privileges of the user running the application using the newt library
(CVE-2009-2905).
